Cryptography is used broadly in the digital age, making our communications secure, ensuring our data is safe, and enabling secure transactions on which we rely daily. Our reality is connected, we send an email without thinking about all the underlying protocols, we buy online, and we check the weather on our fridge. Utilizations are countless and so is

QKD-Enhanced Cybersecurity Protocols
Security of QKD is guaranteed by the quantum mechanics laws rather than unproven assumptions employed in computational cryptography. Unfortunately, the secret-key rates are way too low and transmission distances are limited. The post-quantum cryptography

Lattice‐based cryptosystems in standardisation processes: A survey
The current widely used public‐key cryptosystems are vulnerable to quantum attacks. To prepare for cybersecurity in the quantum era, some projects have been launched to call for post‐quantum alternatives.

NTT and Inverse NTT Quantum Circuits in CRYSTALS-Kyber for Post-Quantum Security Evaluation
The emergence of quantum computers threatens current cryptographic systems, and NIST is preparing for the post-quantum era through the post-quantum cryptography (PQC) contest. CRYSTALS-Kyber is a lattice-based cipher suite that is used as a PQC standard.

HybridPKE: A forward-secure non-interactive quantum-safe hybrid key exchange scheme
The schemes submitted to NIST call for standardization of post-quantum cryptography have some common drawbacks in terms of decryption failure probability, scalability, and switching issues from pre-quantum to post- quantum cryptography. In this paper, we
